Eating cranberries to help prevent urinary tract infections is an old home remedy that has stood the test of time. But women who have recurrent urinary tract infections will find more relief from antibiotics, researchers said Monday. An estimated 30% of premenopausal women develop chronic urinary tract infections. A low dose of the antibiotic trimethoprim-sulfamethoxazole is often prescribed to women who have repeated urinary tract infections in order to prevent recurrences. Typically, however, doctors try to avoid long-term use of antibiotics because it can lead to antibiotic resistance.

A new strain of antibiotic-resistant gonorrhea should be enough to scare anyone who's playing the field without full protection. But the worries might not stop there. Like gonorrhea, chlamydia and syphilis are sexually transmitted diseases that are caused by bacteria. And anytime you have a bacterial disease, there's at least some chance that the germs could eventually find a way to outsmart antibiotics. So what are the odds that chlamydia or syphilis could turn into the next super germs?

Japanese and European researchers have identified a new strain of Neisseria gonorroeae that is exceptionally resistant to cephalosporins, the last remaining family of antibiotics available to treat the sexually transmitted disease. Although physicians have identified only a handful of infections by the new strain of gonorrhea, called H041, they fear that its ability to grow even in the presence of the cephalosporins may allow it to spread rapidly throughout the world. "This is a large public health problem and the era of untreatable gonorrhea may now have been initiated," the team wrote in their abstract for the report presented Sunday at a Quebec City meeting of the International Society for Sexually Transmitted Disease Research.

A new strain of methicillin-resistant Staphylococcus aureus, commonly known as MRSA, has been discovered in cows and humans in the United Kingdom and elsewhere in Europe, researchers reported Thursday. The new strain disturbs researchers because it evades one of the most commonly used tests to detect MRSA, which could lead physicians to prescribe the wrong antibiotics to treat the infection. The new strain of the bacterium is still relatively rare and, so far, no deaths have been attributed to it, the team reported in the journal Lancet Infectious Diseases.

In what is being hailed as the biggest breakthrough since the 1960s in treatment for latent tuberculosis — noninfectious TB without symptoms — researchers said Monday that weekly doses of a cocktail of antibiotics can cure the infection in only three months as effectively as the standard treatment of daily drugs for nine months. By reducing the number of pills and shortening the time required for therapy, the new regimen increased the proportion of patients who completed treatment from 69% to 82%. By increasing the success rate of therapy, the regimen should reduce spread of the disease and the risk of inducing resistance to TB drugs, experts said.

Yet another study has found stuff you don't want to eat in stuff that you eat. On April 15, scientists reported that the meat bought at supermarkets is often contaminated with Staphylococcus aureus bacteria that are resistant to antibiotics used to fight human disease. The study, published in the journal Clinical Infectious Diseases, found staph on 47% of 136 samples of beef, chicken, pork and turkey from 26 grocery stores in five U.S. cities. Of those bacteria, 96% were resistant to at least one type of antibiotic and more than half were resistant to at least three.

An antibiotic developed by a San Diego firm received a government panel's backing as a treatment for diarrhea caused by increasingly common bacterial infections often acquired in hospitals and nursing homes. The panel of outside experts convened by the Food and Drug Administration voted 13 to 0 that fidaxomicin, marketed under the trade name Dificid by Optimer Pharmaceuticals Inc., is safe and effective in combating symptoms associated with Clostridium difficile , also known as C. diff . The unanimous vote endorsed the FDA's preliminary findings and increases the chances that the agency will approve fidaxomicin.

After reports that a dangerous drug-resistant bacterium, carbapenem-resistant Klebsiella pneumoniae , or CRKP, had spread to at least 356 patients in Southern California last year, Times staff writer Molly Hennessy-Fiske spoke with Dr. Kavita Trivedi, medical epidemiologist with the California Department of Public Health's Antimicrobial Stewardship Program Initiative, about what can be done to reduce the spread of such drug-resistant "superbugs....

A dangerous drug-resistant bacterium has reached Southern California healthcare facilities, according to a study released Thursday by Los Angeles County public health officials. Researchers found 356 cases of carbapenem-resistant Klebsiella pneumoniae , or CRKP, at healthcare facilities in Los Angeles County, mostly among elderly patients, said author Dr. Dawn Terashita, a medical epidemiologist with the county Department of Public Health. "We think that this is increasing," Dr. Jonathan E. Fielding, the county's public health chief, said of the infections.

An experimental antibiotic called fidaxomicin is more effective than the gold standard drug vancomycin at reducing recurrences of the often-lethal bacterial infection Clostridium difficile , Canadian and American researchers reported Wednesday. The drug's manufacturer, Optimer Pharmaceuticals Inc. of San Diego has applied to the Food and Drug Administration for accelerated approval of the antibiotic, and the agency is expected to reach a decision by the middle of this year. If the drug is approved, it would represent the first new drug to treat C. difficile in at least a decade and "an important advance" in treating the infections, according to Dr. Herbert L. DuPont of the University of Texas School of Public Health in Houston.
